That's pretty hard-nosed. I guess they're within their rights to demand that, but jeeze... Stuff's expensive enough in Alaska, and now you have to get a UL field rep to sticker your relays you put in a JIC enclosure. They should figure out a system for electrical contractors like they have for electric sign builders. A periodic inspection by UL people, and other than that, you put the UL sticker on all your stuff all year.... but not up here, if you put a couple of relays in a box they want to see the UL listing for the assembly.
What year of the NEC is enforced in your area? There is a new Article in the 2005 NEC titled "Industrial Control Panels". The reason for the addition of this Article was the problem of UL listings for the whole assembly. Now you can assemble your own control panel in accordance with this Article.the AHJ in anchorage wont accept ETL, only CSA and UL, we used to have custom junction boxes built for non standard installations. and never had an inspector question the installation. but not up here, if you put a couple of relays in a box they want to see the UL listing for the assembly.
The ground rods I buy don't even have a UL stamp on each rod. The whole bundle of 10 has a cardboard tag with a UL mark.Only time I've ever seen an Inspector here look for a UL listing,is One guy in particular looks for the UL stamp on the ground rods in Residential jobs,just to make sure they weren't cut off.
They drain most of a lightning strike, as their main purpose. Nobody's getting 25 ohms, for most installs. At the voltages that they'll be pressed into service at, I don't think that copper clad or galvanized is going to make much of a difference. Either metal work. All your crap in your house will still get fried, but either metal material will drain enough of the strike to keep your house from burning down. That's my opinion, based on nothing but my generalized skepticism and bad attitude.Interesting Opinion. Care to elaborate?
I know, old thread. However, Intertek does in fact have certified evaluation of any product they list. It is the same process and certification that UL or any other listing service performs. Intertek would be disqualified to list product if they did not follow the rules themselves. UL and Intertek and all of them have certifications to renew and processes to follow.the AHJ in anchorage wont accept ETL, only CSA and UL,
